Maintenance
Proper care is essential for jadeite to maintain its beauty and longevity. Avoid dropping or bumping the jewelry, as it can dull the surface or cause cracks. Always store each piece separately in a soft pouch or box to prevent scratches and damage.
When cleaning, use warm soapy water and gently wipe with a soft cloth. Then, dry it in a well-ventilated area away from direct sunlight. Avoid using harsh chemicals or abrasive materials, which may harm the stone’s finish.
Main Identification Features
Natural Characteristics: Whether raw or polished, jadeite typically shows a unique interwoven pattern known as "cui." This includes larger granular crystals surrounded by fine fibrous crystals. The texture is usually uniform, but the contrast between different parts gives it a natural look.
Stone Flowers: These are small white, fibrous clusters within the jade that appear opaque or semi-transparent. Unlike the more transparent phenocrysts, stone flowers add a subtle texture and depth to the stone.
Color Variation: Jadeite often has uneven coloration, with shades of green, black, pink, cyan, or bean green mixed into a white or pale background. The color tends to be rich and vibrant, with no artificial uniformity.
Luster: High-quality jadeite exhibits a bright, glass-like shine, often described as "greasy" or "oily." This luster adds to its visual appeal and helps distinguish it from other stones.
Density and Refractive Index: Jadeite is dense and sinks quickly in tribromomethane, while other similar stones like nephrite or quartzite float. Its refractive index is around 1.66, higher than most imitation stones, which is a key identification feature.
Inclusions: Natural inclusions such as black mineral spots are common. These often appear as dark specks with a cloudy edge, and the surrounding area may show a deeper green hue, creating the saying “the green follows the black.â€
Water Retention: A notable trait of good jadeite is its ability to hold water. When a drop is placed on the surface, it forms a small bead rather than spreading out immediately.
In summary, the main characteristics of genuine jadeite include irregular color patterns, a strong glassy luster, a distinctive interwoven structure, a cool touch, and consistent color under a magnifying glass. Proper care ensures that your jadeite remains beautiful for generations.
